It's Halo: Reach time again, because it's always Halo: Reach time with some of you. Why not make the most of that time and save yourself some coin on the new "Defiant" map pack by showing off how much you know about the game? Or, you know, how fast you can type a question into Google?

All you have to do is follow @game_on on Twitter, then tune in tonight (and each night thereafter) at 5pm EDT. I'll be there asking trivia questions about the series. The first follower to answer correctly wins a download code (we'll limit that to one code per Twitter account).

A shameless attempt to pick up followers? You betcha. Tell your friends!

Since we're starting today and I have five to give away, we'll do two in a row Friday night. Hey, what else are you doing on Friday?

What's "Defiant"? A map pack out today for 800 Microsoft Points (or $10) that includes three multiplayer battlegrounds. I guess one's set on an orbital station above a planet on fire (6 to 12 players), another's tucked away in a forest somewhere (8 to 16 players), and the third's carved out of a civilian mine (up to 4 players).

If my pithy description's not doing it for you, check out this Defiant map pack walkthrough instead.
